Having starred in hits like Dabangg, Rowdy Rathore and Son Of Sardar, vivacious Sonakshi Sinha who is excited about her upcoming film Lootera with co-star Ranveer Singh, claims that this film will be her best performed film, till date.

Directed by Vikramaditya Motwane, the film Lootera which is inspired by O'Henry The Last Leaf, has been a difficult experience for Sonakshi. "Lootera has been the most difficult shooting experience for me so far. In terms of character, look, performance, locations.. Everything had to be from an era I knew nothing about. There were times while shooting I would wake up and say to myself 'why am I doing this?',” she explains.

However, once she had a glimpse of the trailer and rushes, she was satisfied and felt that all the hard work and struggle was worth it. She says, that she felt like seeing a completely different actress from a different era.

Co-production between Ekta Kapoor's Balaji Telefilms and Anurag Kashyap, Vikas Bahl, Madhu Mantena and Vikramaditya Motwane's production house Phantom, both the leads will be seen in a completely transformed look in this romantic drama, that is set for release on July 5.
